MACHINE FOR MAKING JULEP-TUBES.

SPECIFICATION forming part of Letters Patent No. 733,714, dated July 14, 1903.

Application filed February 14, 1903- Serial No. 143,340. (No model.)

To aZZ whom it may concern:

Be it known that I, STANLEY K. GREEN, of the city of Baltimore and State of Maryland, have invented certain Improvements in Machines for Making Julep-Tubes, of which the following is a specification.

This invention relates to a machine whereby a stripof paper drawn from a roll is wrapped spirally about a rotary mandrel, its edges pasted, and the pasted tube drawn longitudinally off and from the spindle and cut into lengths, as will hereinafter fully appear.

In the description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which- Figure 1 is an exterior side view of the improved machine, and Fig. 2 a top or plan view of the same. Fig. 3 is an end view of Fig. 1 looking in the direction indicated by the arrow in that figure. Fig. l is a reverse side view of a part of Fig. 1 on an enlarged scale. 5 is a sectional View of a part of Fig. 1. Figs. 6 to 17 are enlarged details of the ma chine, hereinafter described. Figs. 18 and 19 illustrate certain modifications in the construction of a part of the machine hereinafter described.

Referring now to Figs. 1 to 1.7, inclusive, of the drawings, 1 is the bed of the machine, supported by suitable legs is a fixed stand erected on the bed 1 and at one end thereof. This stand is shown to the left in Figs. 1 and l is a horizontal shaft adapted to rotate in the upper part of the stand 3. One end of this shaft is bored to receive and hold tightly the mandrel 5, around which the paper strip is spirallylaid, as hereinafter described. The other or rear end of the shaft 1 carries a beveled pinion 7, (see particularly Fig. 6,) the teeth of which are in mesh with those of a beveled gear wheel 9, arranged to turn loosely.

the lower end of the vertical shaft is secured a pinion 16, (shown only by dotted lines in Fig.1, but fully in Fig. 6,) the teeth of which are in mesh with those of a rack-bar 17, fastened to the underside of and projecting rearward from a head 19. The head 19 is seated on the bed 1 and adapted to have a reciprocating motion longitudinally thereof produced as hereinafterdescribed.

From the foregoing description it will be understood that in the'forward and backward motions of the rack-bar 17 the shaft 4, with its mandrel 5,will have an intermittent rotary movement in one direction.

The reciprocating motion of the head 19, before briefly referred to, is derived from the driving-shaft 20 through the medium of the crank 21 and the connecting-rod 22, which connecting-rod is pivoted to the head at 23. (See Fig. 1.)

25 is a second sliding head connected to the first, 19, from which it receives its movement by means of the links 26, (see Figs. 1 and 2,) and by reference to the former figure it will be seen that the bolts which unite the links to the head 25 pass through the slots in the links. Owing to the slotting of the links 26, as described, it will be understood that neither a forward nor a backward movement of the head 19 is communicated instantlyto the one 25, but that in the reciprocation of the two heads they are alternately separated and closed a distance equal to the excess in length of the slots over the diameter of the bolts within them. This independent movement of the heads is availed of to perform an important function of the machine, as hereinafter described.

By reference to Fig. 1 it will be seen that the mandrel 5 extends through an arm 27 of the head 19, through the upper part of the head 25, and terminates at the outer face of a hardened perforated steel plate 29, which forms the forward extremity of the head and has a vertical dovetailed groove 30 therein. (See Fig. 2.)

32 is a bracket (see Fig. 3) bolted to the side of the head 19, having a pin 33 in an inclined position, about which loosely rotates the reel 3i. Around this reel is coiled or wrapped a strip of paper 35, from which the tubes are formed. The coil of paper is denoted by 36.

The end of the paper strip 35 is carried over a conical roller 37, which rotates loosely about a pin 39, forming a part of a bracket 40, attached to the head 19 and wrapped spirally around the mandrel 5, and the angle of inclination of the pin and the position of the conical roller 37 with reference to the spindle, together with the beveled surface 42 of the lug 43, against which the edge of the paper bears, govern the pitch of the paper spiral formed on the mandrel as that device is rotated by means of the mechanism before described.

The hole 46 in the bracket 27, through which the mandrel 5 and its paper covering passes, is enlarged at the forward end and made conical to receive the split conical block 45, which forms the gripping device, (see Figs. 8, 9 and 10,) the two sections of which conical block are connected to the head 25 by means of the plate-springs 47. The length of the platesprings 47 is such that when the heads 19 and 25 are spread apart or separated to the fullest extent the conical split block is removed from contact with the recessed conical surface in the bracket 27, which allows the block to expand and enlarge its central hole 49, and when the said heads are brought toward each other a reverse action is effected and the hole 49 is reduced in diameter. The alternate opening and closing of the hole 4:9 is availed of to intermittently draw the paper tube longitudinally of the mandrel 5, as will fully appear in the description of the operation of the machine which follows. A very nice adjustment of the action of the split conical block, so as to prevent the closing of the same to a toogreat extent, is effected by means of the threaded bolt 50, projecting from the head 25, and the lug on the head 19, as shown particularly in Fig. 1. The bolt 50 is screwed into the head 25 and secured against unscrewing by an ordinary locking-nut.

It has been stated in substance that the approach of the head 19 toward the one 25 in the forward movement of the machine is produced by slotting the links 26, the loose motion thereby obtained being depended upon to effect the grip of the paper tube by the split conical block; but as the exact length of the slots to properly effect this purpose cannot be ascertained until the machine is practically completed the slots are extended toward the left, as in Fig. 1, so that their ends will not touch the bolts which unite the links to the head 25 when the gripping devices grasp the tube. The operation of adjusting the gripping mechanism consists in moving the head 19 toward the one 25 until the proper friction between the grasping-surfaces of the split conical block and the paper tube is obtained, when the bolt 50 is unscrewed until its end comes in contact with the lug on the head 19. The exact position of the other end of the slots is not of the same importance, as the loose motion in the return or backwa rd movement of the machine serves to release the tube, and should the expansion of the conical block be excessive it will not interfere with the proper operation of the machine; the two devices forming a stop.

53 is a glue or paste pot (see particularly Fig. 5) secured to the head 19, through which extends laterally a shaft 54, carrying the roller 55. At one end of the shaft 54 is a ratchetwheel 51, and below this wheel is a rack-bar 56, pivoted at one end to the fixed stand 3. (See Figs. 4 and 5.) The said bar is supported by a stirrup-shaped arm 57, hung loosely on the shaft 54. Friction between the arm 57 and the rack-bar 56 as the latter is moved in either longitudinal direction is produced by means of a spring-plate 59, pivoted to the out side of the arm at 60, whose ends bear against one side of the bar. Tilting of the pivoted spring-plate is prevented by its tongues 62, which enter and rest in a groove 63 in the one side or the outer face of the bar. Stops 64L on the side of the head 19 in connectionwith the tailpiece G5 limit the swinging move ment of the stirrup-arm. When the various parts just described are in the relative positions shown in Fig. l and the head 19 is moved toward the stand 3, the friction between the spring-plate and the rack-bar 56 serves to retain the said arm in the position shown, with the teeth of the bar in mesh with those of the ratchetwheel and the said wheel, together with the shaft 54 and its paste-roller 55, is rotated; but on the return movement of the head the friction referred to causes the stirrup-arm to swing into a vertical position, when the rack-bar falls by gravity and the meshed teeth are disengaged, with the result that the paste-roller is not rotated. It will be understood that the rotation of the paste-roller takes place as the paper strip is wound around the mandrel 5, and as there is a second paste-roller 67 in the paste-pot in contact with the first and whose upper limb is in the path of the paper paste is applied to its edge. The spring-held roller 69 serves to flatten the pasted seam formed by the lapped edges of the paper.

70 is the knife (see Figs. 11, 12, and 13, which are respectively an edge, a side, and a top view of that device) which in connection with the steel plate 29 cuts off that portion of the paper tube which projects through or beyond the head 25. The knife is provided with a tapered hole '72, through which the paper tube projects, and its downward or shearing movement is caused by the spring '74, which bears on its end. The upperend of the knife '70 is seated in the dovetailed groove 30 in the steel plate 29, before referred to, and its lower end slides in a bracket 75, extending from the head 25, as shown particularly in Fig. 1. The lower extremity of the knife 7 0 is rounded, as seen from the side of the machine, (see Figs. 1 and 11), and this rounded portion of the knife in the forwardmovement of the head 25 rides up the inclined upper surface of the lug 77 and has the effect of elevating the knife, so as to bring its hole 7 2 in alinement with the hole in the head through which the paper tube will be projected in the backward movement of the head.

79 is a spring-held latch (see Figs. 11 and 12) in alinement with a second lug 80, (see Figs. 1 and 2,) which is tilted and dragged over the surface of the said lug in the forward motion of the head just described, but which rights itself as it reaches the rounded surface 82. In the backward movement of the head the latch serves to keep the knife in an elevated position until it reaches the end of its stroke, when it passes over the end of the lug and allows the knife to fall to the position shown in Fig. 1 and shear off the projecting portion of the paper tube.

It is necessary that the split conical block 45 should be released from contact with the wall around the conical hole 46 in the bracket 27 before the beginning of the return stroke of the sliding heads, for the reason that the enlargement of the hole if) in the said block, due to the separation of its two sectionsin the spreading of the heads 19 and 25, does not take place at the moment when the crank-pin passes its inner center. I therefore pivot to one side of the connectingrod 22 a springheld toe 83, (see Figs. 1 and 16,) the end or point of which strikes the vertical surface of the lug 8i and moves the head 25 forward independently of the one 19 immediately before the crank reaches the horizontal center line.

A curved spring-plate 87, aface and edge view of which are shown, respectively, in Figs. 11 and 15, is secured by screws to the outer face of the steel plate 2.), with its convex surface bearing against the knife, to take up any loose motion occasioned by wear which might interfere with the proper shearing action of the knife on the paper tube.

lVith the machine in operation and the heads 15) and 25 about to move backward or toward the position in which they are shown in Fig. 1 the mandrel 5, which is in rotation, draws the paper from the reel, which, being connected to the head 19, has a backward movement in common with it and winds the paper strip spirally upon itself, beginning at the free end of the mandrel, and its edges are pasted together. During this backward motion of the heads the two parts or sections of the split conical block are separated, so that in passing over the tube formed as described they will not come in contact with its surface. At the completion of the backward movement of the heads the rotation of the mandrel ceases, and the latch 79 passes over the end of the lug 80 and allows the knife to drop or, rather, to be forced down by the spring 74; but this being the first motion of the heads after the starting of the machine the knife does not perform any work for the reason that the paper tube has not yet been projected beyond the end of the mandrel. Upon the beginning of the return or forward movement of the heads the split conical block closes on the paper tube, and as the movement continues the paper tube, together with the paper roll, is drawn longitudinally of the mandrel and the former carried over and beyond its end, so that during the next and all subsequent baclnvard strokes it is projected through the head 25 and the knife 7 0, and at the completion of each backward movement the knife shears off the projecting portion of the paper tube, which has a length equal to that of the full stroke of the crank 21. At the beginning of the backward motion of the heads there should be sufficient tubing left on the mandrel to produce the friction neces sary to continue the unooiling of the paper from its roll; but should this involve an extreme length of mandrel increased friction may be obtained by making the mandrel of some polygonal shape in cross-section or grooved, as illustrated in Figs. 18 and 19, which represent sections of the mandrel on an enlarged scale. The completed tubes are finally treated with paraffin or some other suitable substance to render them waterproof; but this operation does not enter into the. present invention.
